Error when running show()

[dakomura]

I installed igv-jupyter on conda virtual environment by running the following command and no error occurred.

conda create -n test python=3.7.1
conda activate test
conda install pip
conda install jupyter
pip install igv-jupyter

jupyter serverextension enable --py igv --sys-prefix
jupyter nbextension install --py igv --sys-prefix
jupyter nbextension enable --py igv --sys-prefix

But when I ran the following command on jupyter

import igv
b = igv.Browser({"genome": "hg19"})
b.show()

, jupyter diplayed nothing and I got the following error message in the background.

[IPKernelApp] ERROR | Exception in comm_msg for 943591948d6945bd80c5393589dba4dc

What happened?

I don't know I can't reproduce that. To be clear you are running Jupyter Notebook correct, not Jupyter Lab? Could you share your notebook file?

The problem was solved. What I did was to run jupyter serverextension disable --sys-prefix jupyter_nbextensions_configurator because the error similar to this occurred.

Thank you anyway.
